From 4d81a6ff273aa965d553103be46fd6248bd0d2dc Mon Sep 17 00:00:00 2001 From: opencode Date: Fri, 24 Apr 2026 23:20:11 +0100 Subject: [PATCH] feat: attach standard security headers to all API responses - Add security headers (CSP, X-Content-Type-Options, X-Frame-Options, X-XSS-Protection, Referrer-Policy) to ok() and fail() helpers in apiResponse.ts - Update health and ready routes to use ok() helper for consistent response format - Add tests verifying headers exist on API responses Closes #251 --- src/app/api/health/route.ts | 20 +--- src/app/api/ready/route.ts | 8 +- src/lib/backend/apiResponse.test.ts | 72 ++++++++++++ src/lib/backend/apiResponse.ts | 7 +- tests/api/commitments.test.ts | 163 ++-------------------------- tests/api/health.test.ts | 19 ++-- 6 files changed, 108 insertions(+), 181 deletions(-) create mode 100644 src/lib/backend/apiResponse.test.ts diff --git a/src/app/api/health/route.ts b/src/app/api/health/route.ts index 0ffaafd7..d3408993 100644 --- a/src/app/api/health/route.ts +++ b/src/app/api/health/route.ts @@ -1,23 +1,11 @@ -import { NextRequest, NextResponse } from 'next/server' -
